BACKGROUND We sought to assess the intra- and postoperative haemodynamic effects of continuous perioperative beta-adrenergic blockade combined with phosphodiesterase (PDE) III inhibition and its potential benefits in limiting perioperative myocardial ischaemia in high-risk vascular surgery patients. METHODS Seventy-five patients were randomly assigned to receive tight heart rate (HR) control ...

We report the intraoperative use of esmolol for control of arterial pressure during repair of a traumatic transection of the descending thoracic aorta. A mean infusion rate of esmolol 50.5 micrograms kg-1 min-1 resulted in a decrease in mean arterial pressure to 63 mm Hg and heart rate to 99 beat min-1 and was associated with excellent surgical conditions. The infusion rate of esmolol was titra...

BACKGROUND In order to acquire a high quality image with a low radiation dose, prospective electrocardiogram (ECG)-triggered computed tomography coronary angiography (CTCA) requires a stable heart rate (HR) < 65 beats/min. Esmolol has the advantage of reducing HR. The objective of this article is to assess the value of intravenous esmolol treatment before prospective ECG-triggered high-pitch sp...

We have examined the effects of two different bolus doses of esmolol hydrochloride (Brevibloc) on haemodynamic variables in a placebo-controlled, double-blind, randomized trial. Sixty healthy adult patients undergoing minor orthopaedic surgery were given a standardized general anaesthetic using a laryngeal mask airway. Heart rate (HR), mean arterial pressure (MAP), stroke volume (SV) and cardia...

Background and objectives: The importance of minimizing the exaggerated sympatho-adrenergic responses and QT interval and QT interval dispersion changes that may develop due to laryngoscopy and tracheal intubation during anesthesia induction in the hypertensive patients is clear. Esmolol decreases the hemodynamic response to laryngoscopy and intubation. However, the effect of esmolol in decreas...

BACKGROUND Propofol is associated with pain during injection, which is stressful to patients. The present study was designed to investigate the analgesic effect of pretreatment with remifentanil and esmolol in minimizing propofol injection pain, compared with placebo. METHODS In a randomized, double-blind, prospective trial, 120 patients, scheduled for elective dental surgery under general an...

OBJECTIVE The aim of this study was to evaluate the effects of esmolol infusion on the prevention of haemodynamic responses to tracheal extubation in patients undergoing elective craniotomy. METHODS With approval from the Medical School Ethics Committee at Marmara University and the patients' written consent, 30 patients between 20-65 years of age undergoing elective craniotomy were randomly ...

OBJECTIVE To determine whether the beta blocker esmolol reduces coronary artery wall stress more than the short acting dihydropyridine calcium antagonist nicardipine. DESIGN Randomised double blind placebo controlled trial. SETTING Tertiary cardiology centre. PATIENTS Patients with coronary artery disease. INTERVENTIONS 20 patients were randomised double blind to an infusion of nicardip...

BACKGROUND Rapid increases in desflurane concentration can transiently increase the heart rate (HR). Esmolol possesses a high β1-adrenoceptor selectivity and a short duration of action. This preliminary study aimed at investigating the effects of esmolol on the HR and autonomic modulation during a desflurane-induced HR increase. METHODS American Society of Anesthesiologists physical status I ...

BACKGROUND Administration of a selective β1-blocker, such as esmolol, in human septic shock has demonstrated cardiovascular protective effects related to heart rate reduction. Certain experimental data also indicate that esmolol exerts systemic anti-inflammatory and beneficial effects on vascular tone. Thus, the present study aimed to determine whether a non-chronotropic dose of esmolol maintai...
